RadtooltTip - RadListView problem

Bader

I have a RadListView control which displays RadToolTip by coming over an image. Unfortunatily, the radtooltip is not displayed (It was before) for unknown reason - I recieve an error message (Please view the attached image).. Please view the web page: http://tmonavot.com/Pages/GiftGallery.aspx

Please, note, that this error is a server error (the RadToolTipManager uses AJAX and thus it shows an alert as a standard update panel would do). The error is not directly related to RadControls but to your custom code and general ASP.NET knowledge.This error occurs when the layout of the form being submitted differs from what has been defined on the server side and you have validation enabled. This is usually caused by adding new fields, or items to forms using client script, or the end user submits the form before the page has finished rendering because the server needs the following line

to be correctly rendered before submitting the form. It is a feature to stop people submitting their own forms to your ASP.net page.

What I can suggest is to set the enableEventValidation property to false either in the page directive or in the Web.config. This should fix the problem but I also recommend to search the net for other possible solutions.
